Water soluble polyalkylene glycol oils with high viscosity index and low aerosol toxicity

摘要

The invention relates to ethylene oxide / propylene oxide copolymers which can be obtained by copolymerizing ethylene oxide and propylene oxide with an alcohol having 4 to 12 hydrocarbon atoms and 4 to 12 OH groups, with an ethylene oxide / propylene oxide weight ratio in the copolymer of 40:60 to 60:40 and a molecular weight between 2000 and 10000 g / mol, and their use in lubricant formulations, formulations for fiber preparation and metalworking fluids.
